可能的插件未并行运行方案

标签: java maven cucumber cucumber-serenity

我正在尝试使用Trivago's Cucable Plugin并行运行Scenario。为了在实施项目之前对其进行测试,我下载了该项目。

https://github.com/trivago/cucable-plugin/tree/master/example-project

我尝试mvn clean verify并在目标文件夹中创建了*IT.java个文件,但我注意到这些文件不是并行运行的。

我怎么知道?我在每个语句中添加了睡眠。最大的睡眠时间为15秒,因此总构建时间应为16秒左右,但显示为30(所有方案的所有睡眠总和为2 + 5 + 15 + 8)。

cucable.template

import cucumber.api.CucumberOptions;
import org.junit.runner.RunWith;

@RunWith(Cucumber.class)
@CucumberOptions(
        glue = "steps",
        features = {"target/parallel/features/[CUCABLE:FEATURE].feature"},
        plugin = {"json:target/cucumber-report/[CUCABLE:RUNNER].json"}
)
public class [CUCABLE:RUNNER] {
    // [CUCABLE:CUSTOM:comment]
}

1 个答案:

答案 0 :(得分:0)

关键点:

  • 我们将不会特别混合直接和传递依赖项的版本!这样做可能会导致不可预测的结果。
  • 我们需要专门使用Cucumber-JVM v4.x.x来实现并行执行,而无需使用Cucumber-jvm-parallel或cucable插件
  • 我们将考虑使用v4.2.6进行实施

通过JUnit进行黄瓜并行执行

首先-用一组正确的io.cucumber依赖关系更新POM.xml。

 <dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-junit</artifactId>
    <version>4.2.6</version>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-picocontainer</artifactId>
    <version>4.2.6</version>
</dependency>

要注意的地方-可能会出现类似一切正常的问题,但是测试不能并行执行,并且可能是pom.xml具有testng的直接/传递依赖关系。由于testNG导致Surefire忽略JUnit包装器类。如果您有testng依赖关系,请删除TestNG依赖关系,或者您可以调用2定义2执行-对于TestNG和JUnit并根据需要禁用一个。

第二-根据您的框架需要自定义Runner类

package com.jacksparrow.automation.suite.runner;

import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features = "classpath:features/functional/",
                     glue = {"com.jacksparrow.automation.steps_definitions.functional" },
                   plugin = { "pretty","json:target/cucumber-json/cucumber.json",
                            "junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports"},
                   tags = { "@BAMS_Submitted_State_Guest_User" },
                   junit ={ "--step-notifications"},
                   strict = false,
                   dryRun = false,
               monochrome = true)

public class RunCukeTest {
}

第三-实现了maven surefire插件,该插件实际上可以并行运行测试

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M3</version>
    <configuration>
        <parallel>methods</parallel>
        <threadCount>2</threadCount>
        <reuserForks>false</reuserForks>
        <testFailureIgnore>true</testFailureIgnore>
        <includes>
            <include>**/*RunCukeTest.java</include>
        </includes>
    </configuration>
</plugin>

第四-实现Hooks.java

import cucumber.api.Scenario;
import cucumber.api.java.Before;
import cucumber.api.java.After;

public class Hooks {

    @Before
    public void setUpScenario(String browser){
        //BaseSteps.getInstance().getBrowserInstantiation(browser); your browser setup method
    }
    @After
    public void afterScenario(Scenario scenario){
    // more code goes here  
    }
   }

通过TestNG进行黄瓜并行执行

注意::在以下实现中,我们将从TestNG.xml文件读取浏览器参数

首先-用一组正确的io.cucumber依赖关系更新POM.xml。

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-picocontainer</artifactId>
    <version>4.2.6</version>
</dependency>

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-testng</artifactId>
    <version>4.2.6</version>
</dependency>

第二-根据您的框架需求自定义TestNGRunner类

package com.jacksparrow.automation.suite.runner;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import com.jacksparrow.automation.steps_definitions.functional.BaseSteps;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;

@CucumberOptions(features = "classpath:features/functional/",
                     glue = {"com.jacksparrow.automation.steps_definitions.functional" },
                   plugin = { "pretty","json:target/cucumber-json/cucumber.json",
                            "junit:target/cucumber-reports/Cucumber.xml", "html:target/cucumber-reports"},
                   tags = { "@BAMS_Submitted_State_Guest_User" },
                   junit ={ "--step-notifications"},
                   strict = false,
                   dryRun = false,
               monochrome = true)

public class RunCukeTest extends Hooks {

} 

第三-实现Hooks.java

import org.testng.annotations.BeforeClass;
import org.testng.annotations.Parameters;
import cucumber.api.testng.AbstractTestNGCucumberTests;

public class Hooks extends AbstractTestNGCucumberTests {

    @Parameters({ "browser" })
    @BeforeTest
    public void setUpScenario(String browser){
        //BaseSteps.getInstance().getBrowserInstantiation(browser); your browser setup method
    }
}

第四-根据您的TestNGRunner类和框架的需要,在/ src / test / resources /下更新TestNG.xml。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Testng Cucumber Suite" parallel="tests" thread-count="2">
    <test name="SmokeTest">
        <parameter name="browser" value="chrome" />
        <classes>
            <class name="com.cvs.runner.TestSuiteRunner" />
        </classes>
    </test>
</suite>

第五-您将被设置为以下列任何一种方式使用TestNG运行自动化套件

 -    Run TestNG.xml directly from IDE 
 -    From CMD - mvn test -Dsurefire.suiteXmlFiles=src/test/resources/testng.xml
 -    From POM.xml - Using Surefire Plugin
